SEPARTOR FOR NIINGLED OIL AND WATER.

SPECIFICATION forming part of Letters Patent No. 322,817, dated July 21,1885.

(No model.)

To all whom it may concern:

Be it known that 1, HENRY H. GARRETT, residing at Pittsburg, in thecounty of Alle-r gheny and State of Pennsylvania, a' citizen of theUnited States, have invented or discovered certain new and usefulImprovements in Separators for Mingled Oil and Water, of whichimprovements the following is a specilication.

1n the accompanying drawings, which make 1o part of this specification,Figure 1, Sheet 1,

is a View in perspective of a separator embodying my invention;A Fig. 2,a perspective section through the same at the line .r a: of

Fig. 1, Fig. 3, Sheet 2, a View in perspective I5 illustrating amodication, and Fig. 4 a longitudinal central section through the same,

The object of my invent-ion is to provide simple and effective means forseparating mingled oil and Water, more particularly designed forreclaiming and saving the oil contained in the excess or overflowescaping from the crank-cases of engines in which lubrication of theshaft-bearings and crank-pins is effected by causing the same to rotatein oil and water 2 5 contained in a closed case or receptacle.

'-10 this end my invention consists in a case or chest divided bypartitions into two or more compartments communicating at top with anoverflow-pipe and a waterdelivery 3o pipe,U respectively, andcommunicating one with another by openings in the partitions.

The'improvements claimed are hereinafter fully set forth.

In the practice of my invention I provide a case or chest, 1, which isdivided by vertical partitions, as 2 3 4 5, extending from the bottom toor near the top of the case into a series of separate compartments, 6 78 9. The overflow-pipe 10,1eading from the crank- 4o case of an engineor other source of supply of the mingled oil and water, opens into areceiving-box, 11, which communicates through an opening, 12, near itstop with the first oilcollecting compartment, 6,0f the case 1. The

compartment 6 communicates through an opening, 13, in the partition 2,near the bottom of the latter, with the second compartment,7, which inturn communicates through an opening, 14, in the partition 3 with thethird compartment,8, which is likewise an oil- 5o collectingcompartment, and communicates through an opening, 15, in the partition4,near its bottom, with the fourth or discharge compartment, 9, from thetop of which a waste or discharge pipe, 16, leads the separated water toany suitable point of discharge.

A cock or valve, 19, is connected to the side of the firstoil-collecting compartment, 6, for the purpose of drawing off, from timeto time, the oil that accumulates therein, and said compartmentcommunicates by an opening governed by a valve, 17, which is opened andclosed by a hand-lever, 18, with the second oilcollecting compartment,8, so as to enable the oil in said compartment to pass into thecompartment, to be drawn off therefrom by the cock 19. The compartments6 and 8 may be provided with vertical glass gage-tubes on their outersides, or glass plates 20 may be iitted over vertical openings in thecompartments, in order to indicate the depth of the body of oil thereinand enable the attendant to remove it without drawing off at the sametime any of the subjacent water.

In operation the mingled oil and water enters the receiving-box 11, inwhich the proportion of oil contained in the mixture can be estimated byinspection, and thence passes' through the opening 12 into the firstoi1-collecting compartment, 6,Which it fills nearly to So l the top, thesurplus passing through the lower opening, 13, ofthe partition 2 intothe compartment 7, which it fills, and passes through the upper opening,14, of the partition 3 into the second oil-collecting compat tment, 8,and after 8 5 filling said compartment passes through the lower opening,15, of the partition 4 into the discharge -compartment 9, from which theoverflow of Water escapes through the upper discharge pipe, 16. In thepassage of the 9o mixture through the several compartments the oil isseparated by gravity from the quiescent portions standing therein andrises to the top of the water, increasing lin depth until it reaches thelevel of the cock 19, when it is withdrawn into a proper receptacle foruse. The clear water escapes from the dischargepipe 16 after theseparation of the oi1pro- 3o same.

portionately to the supply, and may be entirely drawn off from thedischarge-chamber from time to time, as desired, by a cock located nearthe bottom of said chamber.

In the modification shown in Figs. 3 and 4 the case lis rectangular inform, and isdivided by a vertical partition, 2, and an inclinedpartition, 4, into two oil-collecting compartments, 6 and 8, and adischarge-compartment,

1o 9. The overflow-pipe l0 is, as in the former case, led into areceiving-box, 1l, having an upper opening, 12, communicating with theirst collecting-compartment, 6, and a discharge-pipe, 16, is connectedto the top of the discharge-compartment 9. The compartment 8communicates with the compartment 9 by an opening, '15, at the bottom ofthe partition 4. Communication may be established either through anupper opening in the partition 2,

2o governed by a valve, 17, or a lower opening governed by a valve, 22,said val ves being connected to a hand-lever, 18, on opposite sides ofits fulcrum, so thatin the movement of said lever the opening of onevalve will effect the closure of the other. In operation the lower valveis left open, and when suiiicient oil has collected in the compartment 6to reach to or below the lower side of the opening governed by the cock19 it is drawn off through the When the oil in the compartment 8 reachesto or below the level of the opening governed by the upper valve, 17,said valve is opened and the oil passes into the compartment 6 to bedrawn off by the cock 19. The compartments are provided with glasslsight-plates 20, to indicate the lower level of the oil, and awaste-cock, 2l, is located near the bottom of the discharge-compartmentsto enable all the waterin the compartment to be drawn oft from the case.

I claim herein as my inventionl. The combination of a case or chest, in-

` closing an oil-collecting compartment having a lowerdischarge-opening, and a dischargecompartment receiving fluid from theoil-col- 5o an oil-delivery cock or valve connected to theoil-collecting compartment, substantially as set forth.

2. The combination of a case or chest, partitions forming aprimary and asecondary oilcollecting compartment, and a discharge-compartmenttherein, passages delivering liquid from the lower portion of theprimary oil-collecting compartment to the secondary, and from the lowerportion of the secondary to the discharge-compartment,a suppl y-pipeleading into the primary oil-collecting compartment, a discharge-pipeleading out ofthe dischargecompartment near its top, a valve governingan opening or-passage from the secondary to the primary oil-collectingcompartment, and an oil-delivery cock or valve connected to the primaryoil-collecting compartment, substantially as set forth. y

3. The combination of a case or chest, partitions dividing said caseinto a series of com# partments communicating alternately near theirupper and their lower ends,a lsupplypipe delivering into a compartmentwhich discharges near its lower end, a dischargepipe leading out of acompartment which receivessupply near its lower end, a valve or valvesgoverning openings between the compartments which discharge near theirlower ends, and a delivery-cock connected to the compartment into whichthe supply-pipe delivers, substantially as set forth.

4. The combination of a case or chest, pai.14 titions forming a primaryand a secondary oilcollecting compartment, and adischargecompartmenttherein, a supply-pipe leading into the primaryoil-collecting compartment, two valves governing openings in thepartition between the primary and secondary compart-v ments,one of saidvalves being located nca-rthe bottom of said partition, and the other ata higher level, a hand-lever connected to said valves on opposite sidesof its fulcrum, so as to alternately open one and close the othervalve,a passage establishing communication between the secondaryoil-collecting compartment and the dischargecompartment near the bottomof their separating-partition, and a discharge 'pipe leading out of thediseharge-compartment near its top, substantially as set forth.

In testimony whereof I have hereunto set my hand.

HENRY H. GARRETT.
